  text: In our work, we have engineered low capacitance single quantum dot photodiodes
    as sensor devices for the optoelectronic sampling of ultrafast electric signals.
    By the Stark effect, a time-dependent electric signal is converted into a time-dependent
    shift of the transition energy. This shift is measured accurately by resonant
    ps laser spectroscopy with photocurrent detection. In our experiments, we sample
    the laser synchronous output pulse of an ultrafast CMOS circuit with high resolution.
    With our quantum dot sensor device, we were able to sample transients below 20
    ps with a voltage resolution in the mV-range.

  text: "The interaction between quantum light and matter is being intensively studied\r\nfor
    systems that are enclosed in high-$Q$ cavities which strongly enhance the\r\nlight-matter
    coupling. However, for many applications, cavities with lower\r\n$Q$-factors are
    preferred due to the increased spectral width of the cavity\r\nmode. Here, we
    investigate the interaction between quantum light and matter\r\nrepresented by
    a $\\Lambda$-type three-level system in lossy cavities, assuming\r\nthat cavity
    losses are the dominant loss mechanism. We demonstrate that cavity\r\nlosses lead
    to non-trivial steady states of the electronic occupations that can\r\nbe controlled
    by the loss rate and the initial statistics of the quantum\r\nfields. The mechanism
    of formation of such steady states can be understood on\r\nthe basis of the equations
    of motion. Analytical expressions for steady states\r\nand their numerical simulations
    are presented and discussed."

  text: <jats:p>High harmonic generation (HHG) from solids shows great application
    prospects in compact short-wavelength light sources and as a tool for imaging
    the dynamics in crystals with subnanometer spatial and attosecond temporal resolution.
    However, the underlying collision dynamics behind solid HHG is still intensively
    debated and no direct mapping relationship between the collision dynamics with
    band structure has been built. Here, we show that the electron and its associated
    hole can be elastically scattered by neighboring atoms when their wavelength approaches
    the atomic size. We reveal that the elastic scattering of electron/hole from neighboring
    atoms can dramatically influence the electron recombination with its left-behind
    hole, which turns out to be the fundamental reason for the anisotropic interband
    HHG observed recently in bulk crystals. Our findings link the electron/hole backward
    scattering with Van Hove singularities and forward scattering with critical lines
    in the band structure and thus build a clear mapping between the band structure
    and the harmonic spectrum. Our work provides a unifying picture for several seemingly
    unrelated experimental observations and theoretical predictions, including the
    anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of
    solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding
    will pave the way for controlling the solid-state HHG and visualizing the structure-dependent
    electron dynamics in solids.</jats:p>

  text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
    hosts different kinds of polarons that significantly affect many of its physical
    properties. In this study, a variety of electron polarons, namely free, bound,
    and bipolarons, are analyzed using first-principles calculations. We perform a
    full structural optimization based on density-functional theory for selected intrinsic
    defects with special attention to the role of symmetry-breaking distortions that
    lower the total energy. The cations hosting the various polarons relax to a different
    degree, with a larger relaxation corresponding to a larger gap between the defect
    level and the conduction-band edge. The projected density of states reveals that
    the polaron states are formerly empty Nb 4d states lowered into the band gap.
    Optical absorption spectra are derived within the independent-particle approximation,
    corrected by the GW approximation that yields a wider band gap and by including
    excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
    spectra with the density of states, we find that the defect peak observed in the
    optical absorption stems from transitions between the defect level and a continuum
    of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
    and other experimentally measurable optical coefficients.

  text: <jats:p>Uniaxial anisotropy in nonlinear birefringent crystals limits the
    efficiency of nonlinear optical interactions and breaks the spatial symmetry of
    light generated in the parametric down-conversion (PDC) process. Therefore, this
    effect is usually undesirable and must be compensated for. However, high gain
    may be used to overcome the destructive role of anisotropy in order to generate
    bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical
    description of the spatial properties of bright squeezed light in the presence
    of strong anisotropy. We investigate a single crystal and a system of two crystals
    with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate
    the generation of bright correlated twin-beams in such configurations at high
    gain due to anisotropy. We explore the mode structure of the generated light and
    show how anisotropy, together with crystal spacing, can be used for radiation
    shaping.</jats:p>

  text: Employing the ultrafast control of electronic states of a semiconductor quantum
    dot in a cavity, we introduce an approach to achieve on-demand emission of single
    photons with almost perfect indistinguishability and photon pairs with near ideal
    entanglement. Our scheme is based on optical excitation off resonant to a cavity
    mode followed by ultrafast control of the electronic states using the time-dependent
    quantum-confined Stark effect, which then allows for cavity-resonant emission.
    Our theoretical analysis considers cavity-loss mechanisms, the Stark effect, and
    phonon-induced dephasing, allowing realistic predictions for finite temperatures.

  text: Density-functional theory within a Berry-phase formulation of the dynamical
    polarization is used to determine the second-order susceptibility χ(2) of lithium
    niobate (LiNbO3). Defect trapped polarons and bipolarons are found to strongly
    enhance the nonlinear susceptibility of the material, in particular if localized
    at NbV–VLi defect pairs. This is essentially a consequence of the polaronic excitation
    resulting in relaxation-induced gap states. The occupation of these levels leads
    to strongly enhanced χ(2) coefficients and allows for the spatial and transient
    modification of the second-harmonic generation of macroscopic samples.
